Race against the clock

My name is Wendy I live in Blackpool, UK I am here sorely to ask for your help. I have been in the U.K since 2003, in 2008 I had to renew my visa and had serious problems with the Home Office to a point they lost my documents and never got any compensation. My problems began then I couldnt find any employment dure to a document I was awarded, being a qualified Care Assistant I had dreams of being qualified as a nurse but all that was taken away. The only jobs I was hired for were agency jobs for factory work. I couldnt get any help and was turned down and the doors closed. With noone to turn to I lost everything I had owned and ended up in the streets for a year with no help.I was tormented so much to this day I still have nightmares, I was almost killed in the street for no reason one night as I was sleeping this guy came from nowhere and dragged me from a step I layed on and my back has never been the same.  Eventually I was hired by an agency that wasn't for permanent jobs made some money to move and start afresh in another city. With the little I had made I was able to stay at bed&breakfast but the money ran out contacted the council couldnt get any help at the same time continued looking for work. I eventually found a job as a Care Assistant in a nursing home for just over a month and was able to pay my rent but was already in arrears. I lost that job I wasnt treated fairly by the staff and felt like I didnt belong, was accused several times of stealing of which it wasnt true. I am a very loyal, honest and hard working person who is just asking for a chance to start afresh now I am in arrears of £1200 and counting I have been given till Monday 30th 2015 to raise £100 failure to do so I will have to leave. I sent my application again for a visa renewal in January and am afraid if I end up in the street I will never receive my visa. I have tried to apply for jobs but noone will give me a chance to get my life back. I am struggling so bad to even get money for food, I have to walk miles to go to interviews all I ever wanted was a chance to get my life back, I have nowhere to turn or nooone to turn to and I fear going back to the streets. I have an  injury that has turned to discomfort causing swelling on my chest and visited the hospital and was turned away. All I ask is your help if anyone has any work as well please give me a chance.
